Rogen, 29, and Miller, 30, started dating in 2004. Rogen revealed his outlandish proposal on Conan O’Brien’s late night show last November, saying he had grand plans to pop the question but discovered that Miller was topless when the time came.

“She was in our closet, changing, and she was literally only in her underpants,” Rogen said on “Conan.” “I had already kind of started [to propose]. … I didn’t picture it like this, and I know she didn’t picture it like this.”
